3.6.2 DS5300 product comparison
Figure 3-70 compares the DS5100 and DS5300. There is no difference between these
models except for the internal front side bus speed. In earlier versions of code, there were
restrictions on cache upgrade and number host channels, which no longer apply with CFW
V7.60.
The DS5100 can be upgraded to the DS5300 by using the Performance Upgrade premium
feature.
